Watch adorable cancer survivor Liam Fitzgerald fist bump Boston hockey players

Hockey fan Liam Fitzgerald, who has Down Syndrome, has become an internet sensation after fist bumping the Boston Bruins in a Youtube video

Eight-year-old Liam Fitzgerald lifted his little fist to bump the Boston Bruins hockey players he idolises, and the internet fell in love.

Fist-bumping Fitzgerald, who has Down Syndrome, and who survived an almost four-year battle with cancer, has become a Youtube sensation, with the video receiving over two-and-a-half million views in just three days.

According to Boston.com, Fitzgerald was diagnosed with Acute Lymphoblastic Leukemia when he was just four, and in the years-long cancer fight made friends with Boston's biggest sports superstars from the Bruins and the Red Sox baseball team.

Just this year, Fitzgerald was a guest of the Bruins in February, of the Red Sox in July, and then again on Tuesday he was invited to watch the Bruins take on the Florida Panthers in a game they won 2-1.

As the players finished their pre-game warm ups and left the ice, each of them passed and fist-bumped Fitzgerald who had his hand extended in anticipation.

The Bruins, who often visit local Children's hospitals, are described by Boston.com as Fitzgerald's "true sports love", and he even dressed for Halloween 2013 as defensive player Adam McQuaid.

Fitzgerald is set to receive daily injections of growth-hormone until he's 18 at least.

His mom Christine Fitzgerald said: "It amazes me, given what he's gone through in his eight years of living. He just goes on."

"Soon, he will start growth hormones every day. It doesn't phase him. He just goes on.

"People tell us he's so cute, and this and that. He was given to us to raise and given to the world to love. He brings joy to people."

The visits were organised with help from the Massachusetts Down Syndrome Congress, which partners the hockey team for an annual charity fundraiser.
